<a href="Memcache.html">Rack::Session::Memcache</a> provides simple cookie
|

|
based session management. <a href="../Session.html">Session</a> data is
|
||
|
|
stored in memcached. The corresponding session key is maintained in the
|
||
|
|
cookie. You may treat <a href="Memcache.html">Session::Memcache</a> as you
|
||
|
|
would <a href="Pool.html">Session::Pool</a> with the following caveats.
|
||
|
|
</p>
|
||
|
|
<ul>
|
||
|
|
<li>Setting :expire_after to 0 would note to the <a
|
||
|
|
href="Memcache.html">Memcache</a> server to hang onto the session data
|
||
|
|
until it would drop it according to it‘s own specifications. However,
|
||
|
|
the cookie sent to the client would expire immediately.

|
||
|
|
</li>
|
||
|
|
</ul>
|
||
|
|
<p>
|

Note that memcache does drop data before it may be listed to expire. For a
|
||
|
|
full description of behaviour, please see memcache‘s documentation.
